i `IPIUDESS FOR IPRODUCING BEGEITAGLES.

Application led `August 21, 1925. Serial No. 51,7112. i

l My invention relates tonew and'useful improvements in the`construction of receptacles and to a new and novel process for pro-`ducing the saine.` y

One ofthe principal objects'of my invention is to provide a receptacleof the charactei' stated having a hollow raised, metal reinforcedportion adapted to receive therein the bridge, iingerpiece or the likeof an eyeglass spectacle korthe like7` forthe purpose of protecting thesame against accidental breakage or damage.

Another object of my invention is the provision of a flexible receptaclehaving a hollow. raised portion within which is arranged and securedarelatively rigidmetal reinforcing member. l y l Another object fofmyuinvention is to provide aprocess for producing such areceptaclewherein both the flexible raised portion and thefmetal`reinforcing member are si- `inultaiieously formed `and secured togtherby means of a single stamping operation.

c Another objectis to provide a process for making a receptacle havingtheabove mentioned characteristics in which the number of operationsnecessaryto complete the saine will` be reduced to a minimum and whereinsuch operations may be easily and quickly performed. f

Other objects and advantages will become more readily apparent duringthe followingY description when taken in connection with tive positionsof various parts at the beginning of the stamping operation.

Fig. 6 is a similar view after ingoperation.

the stampig. 7 shows a sheet of leather or the like which is used informing the case.

tively.

ig.. 8 is a metal blank from which the reinforcingmember is made.

Referring nowto the drawings and more particularly to Figures 1 to linclusive, the iiiunerals 10 and 11 designate respectivelythe front andrear sides of an eyeglass case constructed in accordance with thepresent invention. `These two sides are secured together adjacent theirmarginal edges by means of the stitching 12 which, it will be noted byreference toFigure 1 4entends `only along the two sides and one end ofthe case,

thus leaving the other end openas indicated at 13 to permit'theinsertion of the eyeglass.

`lhe front side 10 is formedwith a hollow raised portion 14 and arrangedwithin the raised portion and secured thereto by means of glue, cementor the like `15 is a metal re-in- `forcing member 16 having the outerwall 17 and the side and end `walls 18 and 19 respec- Securedrespectively to the inner faces of the front and rear sides 10 and 11 bymeans of a suitable adhesive substance 20 is the front andrear lining 21and 22. The lining is of approximately the same size as the sides of thecase and is secured together adjacent its "marginal edges by meansof thesame stitching 12 which secures the sides 10 and 11 together. It will benoted that the front lining 21 `fits snugly within the hollow metalmember 16 and is secured thereto by means of the adhesive` substance 20.

Reference now being had to Figures 5 to 8 inclusive in which I havedisclosed one method for forming the hollow raised metal reinforcedportion of the case, the numeral 23 designa-tes a heated form having therecess 24 therein and above which recess is suspended a punch 25 thelower end portion of the punch and therecess being of the same shapewhile the size of the punch is slightly smallerthan the recess in orderthat it may be received therein during the stamping operation. l

c In forming the front side of the case I rst take a strip of leather orthe like 26 such as is shown in Figure 7 and properly position the saineupon the form 23, the dotted lines 27 in Figure 7 showing` the positionof the recess with resp-ect to the leather after the leather i has beenplaced on the form. c

I then place upon that portion of the material directly above the recessa layer of glue,

cement or the like 28 and then place upon this adhesive substance a flatmetal blank 29 such as is shown in Figure 8.

The punch 25 is then lowered with the result that as it comes intocontact `with theI metal blank itforces thesame together with theleather, into the recess as shown in Figure 6. This action causes theleather to be pushed outwardly to form the raisedzportion 14 and at thesame time forms the metal reinforcing member 16 and forces the same intothe raised portion. When the material is pressed into x three distinctsteps are accomplished by a single operation.

That is to say, as the punch is lowered it presses the leather and themetal into the recess `thus forming the raised portion 14 vand the metal`member 16 and simultaneously securing the two togetherdue to the heatfrom the form. After the front inner :faces of the leat er and of' themetal member.

Ithen form the rear side 11 by simply taking a similar strip of leatheror the like and securing to the inner face thereof the rear liningr 22after which the two sides, together Awith the lining are stitchedtogether adjacent their marginal edges whereby to form a completed case.

While I have disclosed one completedcase,`

also a process for producing the same, it is to be understood thatcertain minor changes in the particular construction of the case may befound advisable `and I therefore, do not wish to be limit-ed to anyspecific details other than those recited in the appended claims.

lFor instance, `while the contour of the raised metal reinforcedrportion is shown as being readily appreciated that this is shown merelyfor the purpose of illustration and that it maybe of any desired shape.

lVhat I claim is 1. The process of makin a flexible receptacle with areinforced rigi portion and having flexible base and cover memberscomprising cupping up a portion of one of the flexible members into anoutwardl extending protuberance removed from al of its edges,adhesively-securinga rigid supporting member of the shape of theprotuberance within the protuberance and securing together the edges ofthe flexible members for a portion of their extent, leaving a portionthereof unsecured and open whereby the whole rece tacle is e'xibleexcept the reinforced protu erance,

the bulge of which extends outwardly from the said cupped up member whenin secured position.

2. The process of makin a flexible receptacle with a reinforced rigiportion and having llexiblebase and cover members compris ing coatingone of said flexible members with an adhesive, placinfr a relativelyrigid metallic member on the coated surface, said metallic member beine'removedfrom all of l the edges of he flexible member, placing laflexible lining over the coated surface and over the metallic member, cuping up fthe flexible memben'the flexible lining and the metallic memberlying therebetween into an outwardly extending protuberance, coating asecond llexible member with adhesive, placing a flexible lining over theadhesive, and

securing together the edges of the two lined flexible members throughouta portion of their extent leaving a portion unsecured and open, theconvexity of the protuberance being on the outside of the cupped memberwhen in secured position, whereby the whole receptacle isllexible exceptthe reinforced cupped up portion.
